This example displays basic statistics about a fetched CSV file, showing the file size in kilobytes, row count, and column count as plain text. It uses JavaScript’s `fetch` API with an async function to retrieve the data from a GitHub-hosted URL, then parses it with `d3.csvParse` to compute the metrics, which are written into a `<pre>` element. The code relies on the D3 library’s CSV parsing and the browser’s native fetch, with minimal styling via an external CSS file.
